We have a Philips scanner. Each DICOM image contains a single slice. The slices are in "tz" order; e.g. if there are 10 slices and 100 time points
image IM_0001 to IM_0100 is all time points of the first slice, IM_0101 to IM_0200 is all time points of the second slice, etc. Put another way,
to3d -prefix CDr1 -time:tz 100 10 2000 alt+z IM_* 00000001/IM_* 00000002/IM_*
When I attempt to feed these same slices to real-time afni with Dimon, Dimon only reads a single slice. afni pops-up a message which seems to indicate that Dimon is reading the header of the first image file (which correctly states that the file contains a single slice) and tells AFNI to construct a dataset with only one slice.
